Solar Window Film
What is Window Film and how does it work?
Window film is basically a self-adhesive polyester film that is applied to the interior surface of glass. It’s used as a “retrofit” for existing glass on automobiles, homes and commercial buildings in order to upgrade solar control and safety.
Solar radiation from the sun is divided into 3 components; visible light we can see, and infrared and ultraviolet rays which we can only feel. As solar radiation strikes a piece of glass, window film acts as a “sunscreen” to block harmful UV rays as well as regulates the levels of heat and light passing through the glass. The amount of heat and light rejected is all dependant on the type of window film selected
There are basically two types of window film – non-reflective or dyed films that primarily absorb solar energy, and reflective or metallized films that absorb as well as reflect solar energy.
Advantages of Solar Window Film
Double and Triple Glazed Windows VS Window Film
Window technology has increased tremendously in the last decade. Double and triple glazed windows are a great choice for new construction or when it comes to using a remodeling contractor to upgrade. The downside is the high cost of both the windows and the window installation labour costs.
Many homeowners looking towards remodeling are wary of the high cash outlay due to the state of the economy coupled with the rising cost of gasoline and food. This is where solar window film comes to the rescue!
Benefits of Solar Window Film
Heat transference – Film conserves energy in both the summer and the winter. In summertime, it reflects thermal energy, as well as a percentage of UV rays back outdoors. In the wintertime, it minimizes warm air transference to the outside world. It's estimated that as much as 70% of a home's heat escapes via contractor grade windows.
Minimize UV rays – As mentioned above, solar window treatments reflect UV rays. The percentage reflected varies by film grade and manufacturer. UV rays play a big part in fading carpet and furniture fabric.
Privacy window film – darker and mirror style films will afford a good degree of privacy for the occupants.
Reduced Energy Costs through lighting, air-conditioning and other appliances, lowering their energy demands.
Care and Maintenance
Once window film has been installed, it’s very common to see a slight haziness and/or small water pockets. This is a normal part of the adhesive bonding process called “curing”. Depending on the film type and weather conditions, it may take up to 30 days for the film to be fully cured. The curing process is slow because the remaining water used in installation must evaporate through the film. Sputtered and heavy security films take the longest to dry and will take longer for any hazy appearance to disappear.
Once the film is dry and cured, it’s then safe for the film to be cleaned. The best cleaner is a simple solution of water and a small amount of soap. Clean the window and then squeegee dry with overlapping strokes in the same way you would clean the outside of your car windows.
You may also clean the film surface with any normal strength glass cleaner. Products with amonia willnot damage the film if used in reasonable quantities and if the film is not left to soak in it. Do not use any abrasive cleaners, industrial strength glass cleaners and/or any other window cleaning tools that may scratch the window film. Remember, the surface of the film is coated with a scratch resistant not scratch proof coating.
Whether it's your home or office, window film provides a variety of consumer benefits to make your life more pleasurable and secure.
We break it down to basically 7 Reasons Why to Choose Window Film:
Decrease Heat - Window film is the most efficient way to reduce unwanted solar heat transferring through your windows. It can provide up to 78% heat reduction versus untreated glass, while controlling hot spots and cooling off sun-drenched areas in your home or office.
Reduce Fading & Health Risks - Window film blocks up to 99%* of UV rays, while also significantly reducing heat. This helps to protect your valuable furnishings from fading and provides a “sunscreen” for your skin against the harmful effects of the sun.
Cut Glare - Whatever the cause - direct sun, reflections from snow, water or surrounding buildings - there is a perfect window film solution to help reduce annoying glare.
Enjoy Energy Savings - Reducing temperature imbalances caused by extreme sunlight is why so many designers, architects and building engineers desire window film. Reducing heat loss will increase HVAC efficiency and lower energy costs.
Increase Safety - Accidents, environmental effects and vandalism can instantly turn a pane of glass into life-threatening shards. Window film can act as a “safety net” by holding shattered glass together.
Enhance Appearance - Whether it's a contemporary look or a uniform design, there's a choice of window film products that can aesthetically complement the exterior of a home or office building.
It's Fast and Easy - Professional installation is quick and simple. There’s minimal disruption to one’s daily lifestyle or work schedule.
